The global semiconductor shortage has finally started to bite at Toyota Motor Corp., highlighting how a resurgence in Covid-19 infections from the Delta variant is now stifling chip manufacturing in Southeast Asia, worsening a parts crisis for car companies. Japan's largest car maker said Thursday it was cutting production in the country by 40% in September because of a shortage of semiconductors, highlighting how the scarcity is hitting even the best-prepared companies. Ford Motor Co. and General Motors Co. also said this week they are scheduling more downtime at several North American factories, in part because virus-related restrictions overseas are further adding to chip-supply constraints. For much of this year, the chip-shortage challenges in the auto industry have largely stemmed from car companies miscalculating how quickly demand for new cars would bounce back and not ordering enough semiconductors.

Does this information indicate a change in demand OR a change in quantity demanded? Also, does the information indicate a change in supply OR a change in quantity supplied? What would a graph look like for this information?
